LIMEKILN.

Specification forming part of Letters Patent No. 22,239, dated December7, 1858; Reissued March 8, 1870, No. 8,877.

To all whom 'Lt may concern:

Be it known that I, CLARK D. PAGE, of the city of Rochester, in thecounty of Monroe and State of New York, have invented certain new anduseful Improvements in Limekilns, of which the following is a full andaccurate description, reference being had to the accompanying drawings,making part of this specification, and to the letters of referencemarked thereon, same letters referring to like parts in both figures.

Cf said drawings Figure 1 is a vertical section of my improved limekiln, and Fig. 2 is a horizontal section of the same on line a Z) Fig.1.

The nature of this invention consists in so constructing the cupola andarranging the flues that a portion of the flame and hot gases arisingfrom the combustion of the fuel will be deflected toward the centerafter passing around the outside. of the limestone and an other portionwill pass directly to the center, thus causing all the limestone tobecome equally and intensely heated. Thus on inspecting Fig. 2 it willbe seen that the fines F pass in diagonally but directly toward thecenter of the kiln, while the fines E passing inward at a tangent to thecurved projections e and (Z, the heated gases are deflected toward thecenter by the curved sides of the kiln, (which is here contracted in themanner shown in plan in Fig. 2,) so as to deflect or guide all the heatfrom the tines E to the center of the kiln where itis most needed. Inthus passing through and around the limestone at the sides however itnecessarily heats it sufficiently to calcine it and thus a high andequable temperature is maintained throughout all the limestone at thelevel of the entering in of the flues. The projections at e and (Z whichdeflect the heat to the center are continued for a short distance aboveand below this level and are then gradually merged in the general curveof the interior of the kiln as will be seen from Fig. 1.

Having thus described my invention what I claim therein as new anddesire to secure by Letters Patent is,

The construction of the cupola with the sectional form shown in Fig. 2combined [Fnzsr PRINTED 1911.]
